The safety belt locks if there is a sudden stop or a
crash, or if you pull the belt very quickly out of
the retractor.
{CAUTION:
You can be seriously hurt if your shoulder
belt is too loose. In a crash, you would
move forward too much, which could
increase injury. The shoulder belt should
t against your body.
To unlatch the belt, push the button on the buckle.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide
added safety belt comfort for older children
who have outgrown booster seats and for some
adults. When installed on a shoulder belt, the
comfort guide positions the belt away from
the neck and head.
56

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are located on the retractor
part of the safety belts. They help the safety
belts reduce a person’s forward movement in a
moderate to severe frontal, near frontal, rear
or side crash, or a rollover.
Pretensioners work only once. If they activate in
a crash, you will need to get new ones, and
probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 107.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your dealer
will order you an extender. It is free. When you
go in to order it, take the heaviest coat you
will wear, so the extender will be long enough for
you. To help avoid personal injury, do not let
someone else use it, and use it only for the seat it
is made to t. The extender has been designed
for adults. Never use it for securing child seats. To
wear it, just attach it to the regular safety belt.
For more information, see the instruction sheet that
comes with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats
should wear the vehicle’s safety belts.
If you have the choice, a child should sit in a seat
that has a lap-shoulder belt and get the additional
restraint a shoulder belt can provide.
Q:What is the proper way to wear
safety belts?
A:If possible, an older child should wear a
lap-shoulder belt and get the additional
restraint a shoulder belt can provide. The
shoulder belt should not cross the face
or neck. The lap belt should t snugly below
the hips, just touching the top of the thighs.
It should never be worn over the abdomen,
which could cause severe or even fatal internal
injuries in a crash.
Accident statistics show that children are safer if
they are restrained in the rear seat.
In a crash, children who are not buckled up can
strike other people who are buckled up, or can be
thrown out of the vehicle. Older children need
to use safety belts properly.
61

{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt can not properly spread the
impact forces. In a crash, the two children
can be crushed together and seriously
injured. A belt must be used by only
one person at a time.
Q:What if a child is wearing a lap-shoulder
belt, but the child is so small that the
shoulder belt is very close to the child’s
face or neck?
A:If the child is sitting in a rear seat outside
position, move the child toward the center
of the vehicle. If the child is sitting in the
second row center position, move the child
toward the safety belt buckle. In either case, be
sure that the shoulder belt still is on the child’s
shoulder, so that in a crash the child’s upper
body would have the restraint that belts
provide. SeeRear Safety Belt Comfort Guides
on page 56. If the child is so small that the
shoulder belt is still very close to the child’s face
or neck, you might want to place the child in a
rear seat that has a lap belt, if your vehicle
has one.
62

{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the
belt in this way, in a crash the child might
slide under the belt. The belt’s force
would then be applied right on the child’s
abdomen. That could cause serious or
fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just
touching the child’s thighs. This applies belt force
to the child’s pelvic bones in a crash.
63

The restraint manufacturer’s instructions that
come with the restraint, state the weight and
height limitations for a particular child restraint.
In addition, there are many kinds of restraints
available for children with special needs.
{CAUTION:
Newborn infants need complete support,
including support for the head and neck.
This is necessary because a newborn
infant’s neck is weak and its head weighs
so much compared with the rest of its
body. In a crash, an infant in a rear-facing
seat settles into the restraint, so the crash
forces can be distributed across the
strongest part of an infant’s body, the
back and shoulders. Infants always
should be secured in appropriate infant
restraints.
{CAUTION:
The body structure of a young child is
quite unlike that of an adult or older child,
for whom the safety belts are designed. A
young child’s hip bones are still so small
that the vehicle’s regular safety belt may
not remain low on the hip bones, as it
should. Instead, it may settle up around
the child’s abdomen. In a crash, the belt
would apply force on a body area that is
unprotected by any bony structure. This
alone could cause serious or fatal injuries.
Young children always should be secured
in appropriate child restraints.
